What is a key pair?

A key pair in cryptography refers to a pair of cryptographic keys that are mathematically related to each other. It consists of a public key and a private key. The public key is shared with others and used for encryption, while the private key is kept secret and used for decryption. The key pair is used in asymmetric encryption algorithms, such as RSA, where the public key is used to encrypt data and the private key is used to decrypt it.
